Licensing Requirements and Limitations for VRRP

Licensing Requirements and Limitations for VRRP

Involved Network Elements

Other network elements are required to support VRRP functions.

Licensing Requirements

VRRP is a basic feature of a switch and is not under license control.

VRRP6 can be used only on the device enabled with IPv6. IPv6 requires a license. By default, IPv6 of a newly purchased device is disabled. To use IPv6, apply for and purchase the license from the equipment supplier.

Feature Limitations

  • In V200R003 and earlier versions, VRRP can be configured only on the VLANIF interface.

    In V200R005, VRRP can be configured on the VLANIF interface and Layer 3 Ethernet interface.

    In V200R006 and later versions, VRRP can be configured on the VLANIF interface, Layer 3 Ethernet interface, Dot1q termination sub-interface, and QinQ termination sub-interface.

  • Starting in V200R010, VRRP6 can be configured on Dot1q termination sub-interfaces or QinQ termination sub-interfaces.
  • Switches of a VRRP group must be configured with the same VRID.
  • VRRP groups must use different virtual IP addresses. The virtual IP address of a VRRP group must be on the same network segment as the IP address of the interface where the VRRP group is configured.
  • If each switch in the VRRP group uses a different VRRP version, VRRP packets may fail to be transmitted. When a VRRPv3-enabled switch and a VRRPv2-enabled switch belong to the same VRRP group, run the vrrp version-3 send-packet-mode { v2-only | v2v3-both } command to configure the switch to send VRRPv2 packets.
  • If both VRRP and static ARP are configured on a VLANIF interface, a Dot1q termination sub-interface, a QinQ termination sub-interface, or an Ethernet interface on a device, an IP address mapped to a static ARP entry cannot be used as a virtual IP address. If a VRRP virtual IP address is an IP address mapped to a static ARP entry on the device, the device generates incorrect host routes, affecting traffic forwarding.
  • The virtual MAC address of a VRRP group cannot be configured as a static or blackhole MAC address.
  • In V200R003 and earlier versions, a maximum of 255 VRRP groups can be configured on the switch by default. Starting in V200R005, a maximum of 256 VRRP groups can be configured on the switch by default. Starting in V200R010C00, the set vrrp max-group-number max-group-number command can be used to set the maximum number of allowed VRRP groups.
  • When configuring VRRP in the sub-interface view, pay attention to the following points:
    • In V200R009 and earlier versions, when VRRP is configured on a Dot1q termination sub-interface, only one VLAN can be configured on the sub-interface. When VRRP is configured on a QinQ termination sub-interface, only one PE VLAN and one CE VLAN can be configured on the sub-interface.
    • When configuring the VRRP groups on a VLAN tag termination sub-interface, run the arp broadcast enable command to enable ARP broadcast on the VLAN tag termination sub-interface.
  • The ARP aging probe packets sent by a VRRP device uses an interface IP address, instead of a virtual IP address, as the source IP address.
